Banana (Musa acuminate) has been popular among consumers worldwide due to its rich nutrients and minerals. However, bananas are highly susceptible the physical biological factors that lead postharvest loss during transportation storage. In this work, novel sodium alginate (SA) films incorporated with silver nitroprusside nanoparticles (AgNNPs) were prepared extend shelf life of through antibacterial antioxidant coating. The results exhibited AgNNPs cubical their size was <500 nm, metal composition being Ag Fe. Additionally, incorporation in SA film seen FE-SEM zeta analysis, an average about 365.6 nm. Furthermore, functional crystalline properties assessed FTIR XRD. Transmittance testing SA-AgNNPs confirmed they have good UV barrier properties. excellent high activity against foodborne pathogens including L. monocytogenes, S. enterica, E. coli at concentration 500 µg/mL. Moreover, storage bananas, nanocomposite coatings act as a microbial contamination slow down ripening bananas. As result, compared SA-coated uncoated SA-AgNNPs-coated lowest weight total bacterial colonies, thus greatly extending life. Particularly when coated films, colonies (TBC) banana peel pulp low 1.13 × 103 51 CUF/g on ninth day storage, respectively. Our work offers efficient strategy improve quality period, extensive applications fruit preservation food packing.
